Temperature Compensated
The 1230 is a high performance temperature
compensated, piezoresistive silicon pressure sensor packaged in
a dual-in-line
configuration. It uses Measurement Specialties’
proprietary UltraStable™ die to provide excellent performance
and long-term stability over wide temperatures.
Integral temperature compensation is provided over a
range of -20°C to +85°C using laser-trimmed resistors. An
additional laser-trimmed resistor is included to normalize
pressure sensitivity variations by programming the gain of an
external differential amplifier. This provides sensitivity
interchangeability of ±1%. Absolute, differential and gage
pressure ranges from 0-15 to 0-100 psi are available. Multiple
lead and tube configurations are available for different
applications.
Please refer to the 1210 and 1220 for information on
products with operating pressures less than 0-15 psi. For voltage
excitation, please refer to the Model 1240.

Notes
1.
Ratiometric to supply current. Span for 2PSI is 30 to 60mV.
2.
Best fit straight line. Non Linearity for 2 PSI is ±0.2% and 5 PSI is ± 0.5%.
Maximum temperature error between -20°C and +85°C with respect to 25°C.
3.
4.
Short term stability over 7 days with constant current and temperature.
5.
Long term stability over a one year period
with constant current and temperature.
6.
For a zero-to-full scale pressure step change.
7.
2X maximum for 100 psi device.
8.
For pressures ranges below 15 psi, compensated temperature range is 0
